Tert. Quatern. Geol., 36(1-4): 3-8. Leiden, December 1999. The Clavilithes 1840 and 1904 the and fasciolariid gastropod genera Swainson, Rhopalithes Grabau, have same type species hence are The situation used the for objective synonyms. is complicated by the fact that most authors have wrong type species designation Clavilithes and thus most of the species which are actually Clavilithes (s. str.) have been placed in Rhopalithes. Most ofthe species presently regarded in in asClavilithes (s. str.) must fact be placed a differentgenus or subgenus: Clavellofusus Grabau, 1904 is used for this purpose.

In 1823, on the footsteps of Alberto Fortis (1778), Alexandre Brongniart drew stratigraphic sections and collected fossils in the Vicenza province, assigning the Bolca and Roncà invertebrates to one and the same geological interval. In the newly introduced 5~`[` Paris Basin. This meant to Brongniart that they belonged to the older Tertiary, and were distinct from the fossil shells described by Giambattista Brocchi in 1814, typifying the younger Tertiary (Rudwick, 2005). “I can relate the calcareous-trappic terrains of Northern Italy to the lower formation, the most ancient of the upper sediment [i.e., the Tertiary]. I’m struck by the analogy between these two terrains, their utter similarity under almost any aspect. Nothing of the lower terrains of the Parisian limestone is missing in Bolca, Roncà, etc.

New material collected from the recent excavations has prompted a reappraisal of the mollusc fauna of this site. This is reviewed along with material collected during the working life of the brickworks and now held in the Natural History Museum, London. The mollusc fauna consists of 146 species and is listed in systematic order, with an indication of local stratigraphic range and palaeoecological interpretation. The taphonomy of the mollusc fauna is discussed, and a number of notes given detailing taxonomic revisions. Three new species of bivalve are described: Semeloidea curryi, Siliqua kingi and Abra (Syndosmya) cygnea and three gastropods: Entomope semipunctata, Solariorbis lawsoni and Epalxis kempi. Lectotypes are designated for Eopleurotoma simillima crassilinea and Microdrillia tricincta. The majority of the fauna is illustrated photographically, in most cases for the first time. P.

  • The Largest Known Cowrie and the Iterative Evolution of Giant Cypraeid Gastropods Stefano Dominici1*, Mariagabriella Fornasiero2 & Luca Giusberti3
    www.nature.com/scientificreports OPEN The largest known cowrie and the iterative evolution of giant cypraeid gastropods Stefano Dominici1*, Mariagabriella Fornasiero2 & Luca Giusberti3 Based on the fossil record, we explore the macroevolutionary relationship between species richness and gigantism in cowries (Cypraeidae), the best-studied family of gastropods, with a global diversity distribution that parallels that of tropical corals, mangroves and seagrasses. We introduce Vicetia bizzottoi sp. nov. based on a Priabonian fossil found in northeastern Italy, the largest documented cowrie found so far and the youngest of a lineage of Eocene Gisortiinae species. The Gisortiinae stratigraphic record in western Europe indicates that species selection favoured large size and armouring of the shell. Palaeoecology and per-stage species richness suggest that gigantism occurred in peripheral habitats with respect to diversity hotspots, where smaller species were favoured. The Eocene–Oligocene boundary was marked by a turnover and the Chattian global warming favoured small-sized species of derived clades. Species selection leading to gigantism is further documented in Miocene lineages of Zoila and Umbilia, in the southern hemisphere, two extant genera distributed at the periphery of modern diversity hotspots, suggesting that the negative relationship between size and diversity is a recurring pattern in the evolutionary history of cowries. This palaeontological evidence is projected onto the existing hypotheses that explain analogous biogeographic patterns in various other taxa. Likewise, body size-species richness negative relationship was possibly driven in cowries by physiological, ecological and life history constraints. Covariance between community species richness and body size of resident species have been studied in a variety of marine invertebrates, suggesting diferent relationships of these two important ecological traits.

  • New Mollusks from the Lower Middle Eocene Llajas Formation, Southern California

Natural History MubOijui —-r- ^ , , 4 , ^c^uxVvSLA l^^U Of Los Angeles County C V ISYgrteferate Paleontology JOURNAL OF PALEONTOLOGY, V. 57, NO. 2, p. 354-362, 2 FIGS., MARCH 1983 NEW MOLLUSKS FROM THE LOWER MIDDLE EOCENE LLAJAS FORMATION, SOUTHERN CALIFORNIA RICHARD L. SQUIRES Department of Geological Sciences, California State University, Northridge 91330 ABSTRACT—Five new mollusks are described from shallow-marine deposits of the lower middle Eocene Llajas Formation, northeastern Simi Valley, southern California. Most of the mollusks are confined to a 1-m-thick bed informally known as the "Stewart bed" and are part of an Eocernina- Turritella-Crassatella community. Cymatium (Septa) janetae n. sp. is at present the earliest species worldwide referable to Septa. Ranella katherineae n. sp. is one of the earliest West Coast species of Ranella s.s. A new species of Clavilithes occurs with C. tabulatus (Dickerson); C. tabulatus was previously regarded as being of early Eocene age only. Pinna llajasensis n. sp. is conspecific with Pinna n. sp. Vokes from the middle Eocene Domengine Formation of central California. A partial phragmocone of a spiruli- morph sepiid, family indeterminate, is the first record of a sepiid in the Eocene of western North America. INTRODUCTION phologic features are well preserved (Squires, THE new mollusks reported in this study were 1981). Such fossils constitute a residual (or collected from the lower middle Eocene Lla- winnowed) community as defined by Fager- jas Formation, southwestern Santa Susana strom (1964).
